Habisoft published a series of ports from CPC that expanded the PCW library with sound: ''Abbey of Crime''; ''Hero Quest''; ''Knight Lore''; ''Pac Mania''; ''Spirits''
Later, it standardized the possibility of ports from the ZX Spectrum to PCW: ''Movie''; ''Fat Worm''; ''Nonamed''; and ''Phantomas2/Vampire'', which used the PCW's buzzer as the Spectrum's beeper. Some also incorporated AY music.
The conversion trail was followed by Kachorro in its Spectrum ports of ''Barbarian'', ''Coliseum'', and ''Xecutor''.
